My invention relates to improvements in bed bottoms and more perticulorly to the class known as woven wire bed bottoms.

in. order that two persons lying on a woven wire bed bottom of the usual construction lllfty not roll or move toward the center of the bed, 'it is generally.- necessary that the central portion of the woven wire bottom be reinforced or rendered less flexible than the side portions of the bed bottoni.

.lt is the object of-this invention. to provide on improvement in such bed bottoms by so constructing the bed bottom that the tension ht the longitudinal center shall be stronger then st the sides, sothet when two persons are occupying a. bed having my improved woven wire bottom, they will not roll toward the center, and so that when one person is of it less weight than the other each can keep his position in bed. without inoomnioding the other.

My invention is embodied in the construction, arrangement and combination of parts as will be hereinafter fully described and Pointed out in the claims, reference being 1nd to the accompanying drewing in Which' Figure 1 is a top plan view of a bed bottom co'nstructcd in accordance with my invention; Fig. is a vertical transverse section.

" oftbc some; 3 is s trensverse sectional view showing the operation ment.

in the drawing is shown o bed bottom consisting of the usual side rails A end the end bar B, the end bttl'S being secured upon the side rails by nails or screws or other suitable of my improvemeans; the end bars are mode in two parts between which the ends of Woven wire bottom (l are clamped and held by nails or other suitable means; ssid woven wire fabric is turned upon itself at the side edges forming longitudinal pockets 0 within which is placed a rope D which serves to strengthen the edges.

The woven wire febric is of e width somewhet greater than the distance between the side rails end the central portion is folded over upon itself in opposite directions forming two lint folds slid within the splice formed betwcenl the upper surfsce of the bottoin snd the folded over portions longi tudinzi-l rbpeh if?) E ere placed and retnin the folds in lace after they are folded down list on the ed'bottom; this formetionlceves the longitudinsl cdntrsl iportion of the bed I bottom slightly elevated. the woven wire fabric is such that the folds will lie perfectly flat when no weight is on thebed bottom. if new a. person should occupy one side of the bed, the left side The strength of as indicated in Fig. 3, the weight of the person causes that portion of the fabric be tween the left side rail and the center of the bed to sag the left bendfold being drawn toward the center, and its. the rope brsce is immovable the under ply'of the fold will slide around the rope brsce and the left llg nd portion of the bottbm will assumea position similar to that shown in Fi 3, thus the person occup ing that side of the bed cannot roll towem the center. If both sides of the bed are occupied the some action takes piece on both sides of the center only in it less degree on each side and tending to equalize the strain.

I clain1:

l. A bed bottom consisting of side mils and end bars and is woven wire fabric contiriuous from side to side and folded upon itself to form a movable fist fold its longitudinel center. i

2. A bed bottom consisting of side rails and end bars, and a woven wire febric continuous from side to side and folded upon itself at its longitudinal center forming two independent spring sections on each side of said center.

3. A bod bottom consisting of side rails and end bars, a woven wire fabric secured to the end rails and folded upoii itself at its longitudinnl center, and longitudinal ropes located between the folded over portion and the upper surface of the woven wire fabric.

4. A bed bottom consistin of side rolls and end bars, a woven wire fa ric secured to said end bars, said fabric bent to lie in a flat fold at each side of the longituonnn center, .c'nd longitudinal ropes held within the space ,between said folds and the upper-surface of the fabric bottom.

5. A bed bottom consisting of side mils and end bars, a woven wire fabric secured to said end bars, the side edges of said fsbric folded upo'- itself, it rope disposed within said folded back edges, the central portion .at their ends to the end bars and lying between the flat folds and the upper surface of Q the 'wil-e fabric.

6. A bed bottom consisting of side rails and end bars and a woven wire fabric secured to said end bars and of a width greater than the distance between the'side rails the surplus width disposed to form a section extending on both sides of the longitudinal center of the bed bottom and lie in a fiat plane above that of the body portion of wire fabric.

7. A bed bottom consisting of side rails and. end bars and a continuous woven wire fabric rigidly secured at its ends to said end bars, the width of said fabric being greater than the distance between the side rails, the surplus bein disposed to form a fiat fold extending on daoth sides of the longitudinal center of the bed bottom, and each side section of the fabric bottom susceptible of indeendent deflection below the plane of the bed ottom.
